Summary:
This port includes the rudimentary latencies that were provided for
the Cortex-A53 Machine Model in the AArch64 backend. It also changes
the SchedAlias for COPY in the Cyclone model to an explicit
WriteRes mapping to avoid conflicts in other subtargets.

This adds a second implementation of the AArch64 architecture to LLVM,
accessible in parallel via the "arm64" triple. The plan over the
coming weeks & months is to merge the two into a single backend,
during which time thorough code review should naturally occur.
Everything will be easier with the target in-tree though, hence this
commit.
